Playa-Lunette Systems

Lunettes are dunes found along the southern margin of some larger playas.

Playa-lunette systems (PLSs) are common features in semi-arid and arid regions around the world, and they are particularly abundant on the High Plains of the central United States.

These systems are especially useful for environmental reconstructions because they are influenced by fluvial, lacustrine, and eolian process, with the dominant geomorphic process at a given time being dependent upon prevailing environmental conditions.
